Short summary
Floating offshore wind turbines make wind resources in deeper waters accessible. However, these systems are more complex and costly than fixed-bottom wind turbines and require further optimization to reduce cost. This study analyzed the effect of aeroelastic modeling fidelity on the design of the floater and the wind turbine controller. The results showed that an increase in fidelity resulted in lighter platforms, influenced controller parameters and led to lower costs overall.
